Across 172 studies, fit with the job, organisation, group and supervisor related to how people feel about their work and how it goes.
Why it matters when the plan changes
Performance is often discussed as a property of the person. Research on fit treats it as a property of the match. Amy Kristof-Brown, Ryan Zimmerman and Erin Johnson's 2005 meta-analysis of 172 usable studies, with 836 effect sizes, examined fit with the job, the organisation, the group and the supervisor, and found relationships with attitudes and work outcomes that generalised broadly across situations.
The tension is that fit is easy to misuse. Selecting for fit with the current organisation can reproduce the past and screen out the difference a new strategy needs, and fit used without qualification becomes a polite word for similarity. The useful question is fit with what: which role, team, supervisor and demand, and whether those are the ones the organisation is moving towards. Fit is always fit with something specific, at a specific time.
In practice
A company moving into a new market shortlists two candidates to lead it. One fits the current leadership team closely; the other fits the demands of the new market better and the team less well. Treating fit as several levels at once makes the trade-off explicit, and shows what support the second candidate would need to succeed.
Evidence
Person-environment fit is the degree to which individual and environmental characteristics match.

What it cannot tell you
Fit research shows associations averaged across many settings, and their strength varies by type of fit and outcome. It does not show that fit can be measured precisely for one person, and fit with a current organisation can be the wrong target when that organisation is meant to change.
Questions
Research usually distinguishes fit with the job, meaning demands and abilities or needs and supplies; with the organisation, usually values; with the work group; and with the supervisor. Amy Kristof-Brown and colleagues' 2005 meta-analysis examined all four and treated each as a distinct relationship.
Broad rather than precise. The 2005 meta-analysis drew on 172 usable studies and 836 effect sizes, and nearly all of its credibility intervals excluded zero, indicating that the relationships generalise across situations. Effect sizes vary with the type of fit and the outcome studied.
Cultural fit is one part of it, usually fit with the organisation's values. Person-environment fit is the wider idea and includes fit with the job, the group and the supervisor. Treating cultural fit as the whole picture overweights similarity and ignores whether the person can do what the role demands.
Yes, when the environment being fitted is the one the organisation is trying to leave. Selecting people who resemble the current team can entrench the previous strategy and narrow the range of perspectives, so fit should be judged against the role and the plan the organisation is moving towards.
It relates to performance and to attitudes, with strength varying by the type of fit. That makes fit a useful part of a judgement about a person in a setting, but not a substitute for evidence about the specific demands of the role and the conditions that surround it.
